While often shown without the Spanish Coat of arms, the official flag of Spain contains it. Many embroidered patch makers will leave this crucial element off and create an iron-on flag patch that is just three stripes. That is because the embroidery on this patch is so hard to achieve with so many colors and such tiny stitching. Compare this parche (Spanish for patch) with others and the quality of this iron-on emblem will be easy to see.
